The Dual XHDR6435 is a cheaper version of the Dual XHD6430. Both are in-dash radio receiver head units that fit into single-din openings. However, the Dual XHDR6435 is only HD-radio ready, and requires the HD radio component to have equivalent features. It can playback MP3/WMA files off of a CD or USB drive, and it can directly control an iPod over the USB port. However, due to the lack of an HD radio, the iTunes tagging features are only useable if there is the additional HDM90 HD radio module. The Dual XHDR6430 does include a regular AM/FM tuner, and it has a two line display capable of showing ID3 tags. It is also Bluetooth-ready
